A connector to provide multiple input-output couplings to a multi-mode opal transmission line without interrupting the radiation flow. A local scrambling cylinder is placed between a multiple input-output bundle and a bidirectional T-coupler. A mirrored surface covers an area of the rod leaving uncovered the core area of the bundle that leads to the T. Input light is reflected by the mirror evenly to provide an optical path between the inputs and the outputs without affecting transmission through the T.
